Struct starlark_map::Hashed

pub struct Hashed<K> { /* private fields */ }

A key and its hash.

Implementations

impl<K> Hashed<K>

pub fn new(key: K) -> Self

where K: Hash,

Create a new Hashed value using the Hash of the key.

pub fn new_unchecked(hash: StarlarkHashValue, key: K) -> Self

Directly create a new Hashed using a given hash value. If the hash does not correspond to the key, its will cause issues.

pub fn key(&self) -> &K

Get the underlying key.

pub fn key_mut(&mut self) -> &mut K

Get the underlying key, as mutable.

pub fn into_key(self) -> K

Get the underlying key taking ownership.

pub fn hash(&self) -> StarlarkHashValue

Get the underlying hash.

pub fn as_ref(&self) -> Hashed<&K>

Convert Hashed<K> to Hashed<&K>.

impl<'a, K> Hashed<&'a K>

pub fn copied(self) -> Hashed<K>

where K: Copy,

Make Hashed<K> from Hashed<&K>.

pub fn cloned(self) -> Hashed<K>

where K: Clone,

Make Hashed<K> from Hashed<&K>, where K is Clone.

impl<'a, K: ?Sized> Hashed<&'a K>

pub fn owned<T>(self) -> Hashed<T>

where K: Equivalent<T> + ToOwned<Owned = T>,

Make Hashed<K> from Hashed<&K>, where T is the owned form of K.

Trait Implementations

impl<K: Clone> Clone for Hashed<K>

fn clone(&self) -> Hashed<K>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K: Debug> Debug for Hashed<K>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K> Deref for Hashed<K>

type Target = K

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<K: Display> Display for Hashed<K>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K: Dupe> Dupe for Hashed<K>

fn dupe(&self) -> Self

impl<K> Hash for Hashed<K>

fn hash<S: Hasher>(&self, state: &mut S)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<K: Ord> Ord for Hashed<K>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<K: PartialEq> PartialEq for Hashed<K>

fn eq(&self, other: &Hashed<K>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<K: PartialOrd> PartialOrd for Hashed<K>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
